Title: Synchronizing system for digital modulation/ demodulation
Inventor: FURUKAWA SUKEYUKI
IPC: H04L7/00
Filed: 1999-12-20
Abstract: PROBLEM TO BE SOLVED: To solve the problem that it takes time to decide a synchronizing point since an eye pattern is disturbed when noise exists in the transmission line of a modulation signal in a system where the maximum eye opening point of the eye pattern in a delay detection circuit output signal is set to be a synchronous point. SOLUTION: Plural sample point are set for the respective symbol periods of a detection output signal and dispersion by the moving average of the respective points is obtained. The minimum value is compared with a dispersion threshold which is previously set. When it is smaller than the threshold, the sample point showing the minimum dispersion value is set to be the synchronous point. When it is larger than the threshold, dispersion is obtained with the average value when the minimum dispersion value is calculated with dispersion is calculated by moving average as the common average value at the sample point. The minimum dispersion value is compared with the minimum value of dispersion by moving average and the sample point showing the smaller dispersion value is set to be the synchronous point.

Filed: 1997-12-27
Abstract: PROBLEM TO BE SOLVED: To efficiently form a solid phase of an immunologically activated substance of an antigen, an antibody, or the like on the well of a micro plate by treating the well of the micro plate with a water-soluble organic solvent and then drying it. SOLUTION: A water-soluble organic solvent means an organic solvent where water can be dissolved by 10 v/v% or higher and is preferably an organic solvent where water can be dissolved by 20 v/v% or higher.

After the treatment, the well of the micro plate is dried. For drying, the water-based organic solvent may be eliminated. After the drying, an immunologically activated substance is immediately formed into a solid phase. By leading a carrier after drying in air, water in air adheres to the surface of the carrier again, thus preferably shifting to solid phase treatment rapidly.
